A Hydraulic Modeling of Loop Pipeline Network with Multiple Heat Sources Based on Graph Theory

摘要：

In order to solve the problem of the dramatic increase in transport energy consumption, it is necessary to study the hydraulic characteristic of DHS(District heating system). Through the survey of DHS in different cities, the form of heating network was founded to be looped pipeline network (LPN) with multiple heat sources. The deficiencies of the past hydraulic model used for the dendritic pipeline network (DPN) are discussed. It was pointed out that LPN with multiple heat sources is spatial network. Graph theory is applied to the establishment of spatial network. Furthermore, a hydraulic model of LPN with multiple heat sources is established. MKP method is used to solve the mathematical model. And an actual engineering case is used to verify the accuracy of the model and its solution method. It provides a theoretic and practical basis for the study of hydraulic characteristic of LPN for DHS.
